* AAP-96178: Fix unified_jobs pagination count to respect RBAC filtering
Non-admin users saw the unfiltered table-wide count instead of the count
matching their RBAC-visible results. Use the same primary-key subquery
approach already proven on the /api/v2/jobs/ endpoint.
* AAP-96178: Add docstrings and mixed-role count test for UnifiedJobPaginator
Clarify the PK subquery approach with expanded docstring and inline
comments per review feedback. Add a functional test verifying that a user
with a mix of JT and inventory roles sees a count matching exactly
their permitted results.
* AAP-96178: Add deduplication test for multiple RBAC access routes
Verify that a job reachable through three overlapping permission paths
(direct JT role, org audit role, and team JT role) appears exactly once
in both results and count.
